Description

This USA Standard Manual Transmission SM465 Bearing Kit (MPN: ZMBK129L) is designed for 1988-1991 GM C/K Series Trucks equipped with an SM465 manual transmission. The kit features an aluminum top cover, a 0.83-inch wide input bearing, and two power take-off (PTO) covers. It also includes synchronizer rings, providing a comprehensive solution for rebuilding or servicing the SM465 transmission. This kit is not compatible with Suburbans from the same year range, which used an earlier SM465 with a cast iron top cover.
